Hi. I have decided to switch from prepaid o2 to contract/post-paid o2. When filling out the online form to conclude the contract, I indicated that I want to keep the old prepaid number. A few days later, I received a SIM without number. I activated it online. However, the SIM does not work and shows “no signal” when I put it in the phone. Meanwhile, the old SIM still works, using the prepaid plan.
What should I do for the new SIM to work with my old number? Are there any additional steps? Or do I just have to wait longer? On the website it says that the card is activated.
Thank you!
